GAS-BURNER.

Specification of Letters Patent.

Patented Apr. 21, 1914,.

To all whom it may concern Be it known that I, JOHN ELLIs, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Gas- Burners, of which the following is a specification.

My invention relates to improvements in gas burners, such as employed in water heaters of the class wherein the water to be heated circulates through suitable coils disposed within a suitable casing above a plurality of burners.

The improvements relate in particular to the form of burner as disclosed in Patent N 0. 979,734, of December 27, 1910, to Adolf Beler.

In the above identified burner, it has been found that the heat to which it is subjected and the dripping of moisture thereon from condensation upon the coils, causes the plate or head covering the face portion of the burner chamber, to become warped and thereby reduce the efficiency of the burner; that, owing to the form of the burner chamber and gas outlet orifices, when a number of the burners are assembled about within the heater, the flame is irregular in depth thereby causing an uneven distribution of heat on the coils and preventing positive ignition of one burner from the other, and

that the dripping of moisture from the coils enters the gas-outlet orifices of the burner and tends to extinguish or diminishthe'gas flames, the object of my present improvements being to provide a burner in which the above disadvantages will be eliminated.

With the above objects in view, the invention consists in the novel form, arrangement, and combination of parts hereinafter set forth in this specification and particularly pointed out in the appended claims.

Inthe accompanying drawings, forming a part of this specification, Figure 1 is a vertical front elevation of the burner, partly in section, and Fig. 2 is a vertical section of the burner taken on the line XX of Fig. 1.

In detail, the burner comprises a tubular portion or stem 1, for connection with the gas supply, and terminating in an inclined head 2 of annular form having a seat 2 thereabout and provided with laterally disposed lugs 23. Upon this head is fitted a '7. This chamber is further burner chamber 4, having laterally disposed lugs 5, registrable with those of said head and to which it is secured by bolts 6, the base portion of said chamber corresponding n outline to that of the head and gradua ting at its upper face portion into a straight surface which terminates in a straight transversely-disposed drip-deflector lip or flange provided with a plurality of elongated gas-outlet orifices 8 extending thereacross in parallel relation with and in close proximity to the deflector 11p and is also provided with an internally progectlng centrally-disposed annular boss 9. Fitted upon the seat 2 within and engaged by the boss 9 of the chamber, is a frustoconical burner cap 10, preferably formed of soap stone, having spaced slits 11 formed thereabout constituting gas outlets. In this form of gas burner, the gas enters and passes up through the tubular stem into and through the slits in the burner cap, into the chamber space thereabout and out through the gas orifices 8. l/Vhen the burners are closely assembled within and about the heater, the outlet orifices 8 of each aline all the way thereabout, thus assuring the gas flames being of regular depth throughout as well as assuring the ready ignition of gas at each and all burners from one another, under all conditions, the dripping of moisture due to condensation on the coils being prevented from entering the outlet orifices by the lip 7 By making the outer head or face portion of the gas chamber integral with the body portion thereof, the warping and resultant leakage impairing the efficiency of the burner, as occurs in the old form of burner where the face portion is made separate and secured thereto, is avoided. Again, the separation of the chamber at the base or rear head thereof, permits the joint between the chamber and said head and the seat for the burner cap to be readily ground upon an emery wheel rather than facing the same by machine tools, as required in the old form of burner, thus saving time and expense in manufacture.

Having thus shown and described my inventlon, what I claim and desire to secure by Letters Patent, is-

gas burner, comprising a tubular gas lnlet terminating at its outlet end in a chamber head, an inverted cup-shaped burner cap seated upon said head over the outlet and provided thereabout With spaced gas outlets, and a gas chamber having an integral head at its face portion also seated upon and secured to the inlet head and inclosing the burner cap, said chamber having a transverselydisposed forwardly-projected flange formed upon the upper face portion thereof, and a gas outlet directly beneath and in parallel relation therewith formed through said face portion.

2,. A gas burner, comprising a tubular gas inlet terminating at its outlet end in an inclined chamber head, a frusto-conical burner cap seated upon said head over the outlet and provided thereabout with spaced slits forming gas outlets, and a gas chamber in- Copies of this patent may be obtained for closing said burner cap and also seated upon and secured to the inlet head, said chamber having a transversely-disposed forwardlyprojecting flange formed upon the upper face portion thereof and a plurality of elongated gas outlets formed through said face portion all of which aline and are in parallel relation with said flange and located directly beneath the same.

In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

JOHN ELLIS.
